Book excerpt: This report presents the results of a communication theoretic model used to analyze the operation of Interferometric Fiber Optic Gyroscopes (IFOG). The IFOG is an all-solid-state rotation-rate sensor employed in miniature inertial measurement units (MIMU). The IFOG can achieve a navigation grade of performance (0.01 degree/hour drift rate) and offers the considerable advantage of reducing instrument costs by a factor of two or more over the current ring laser gyroscope (RLG) technology base. A simplified classical propagation model is used to describe the optical beams employed. Optical signal modulation is impressed with the following goals: (1) increase the linearity of the rotation-rate measurement and (2) mitigate the deleterious effects of the optical scatter noise unavoidably generated by the desired light beams as they traverse the optical pathways of the IFOG. This report deals with goal (1) above. The following are analyzed: (1) AC bias modulation used to linearize the IFOG instrument; (2) closed-loop, feedback operation to extend the dynamic range; and (3) serrodyne operation. The analysis establishes the performance relationships among the appropriate optical signal parameters and allows for their optimization.

Available in PDF, EPUB and Kindle. Book excerpt: This landmark work – considered by many in the field to be THE reference on fiber-optic gyroscopes (FOGs) – provides you with a complete and thorough system analysis of the FOG and remains unmatched by any other single source. Now in its third edition, this fully updated and authoritative book: Gives you access to all the details you need to know about optics, single-mode fiber optics, and integrated optics to fully grasp the design rules of the fiber-optic gyroscope Helps you understand the concepts that have emerged as the preferred solutions to obtain a practical device Guides you through the advances that have occurred in the last seven years since the previous edition was published and how they are implemented in the current FOGs Drawing on 45 years of research and development, The Fiber-Optic Gyroscope, Third Edition, features new content on the relationship between white-noise power spectral density and random walk; Allan variance; testing with optical coherence domain polarimetry; a new simple mechanical model of the thermally induced stresses and related strains in the sensing coil; simple viewing of the reduction of the Shupe effect with symmetrical windings; and comments about dispersion and birefringence dispersion. The book contains over 350 illustrations (including 70 new figures) and many helpful appendixes, and gives you everything you need to understand the fiber gyro. The author is a leading expert in this field and is one of the early pioneers of the practical optical architecture and signal processing technique that is universally used in today’s FOGs. This is a must-have reference for anyone working with FOGs, from students and academics learning about the device, to optoelectronics engineers and professionals needing to stay abreast of the current concepts and recent advances.

Available in PDF, EPUB and Kindle. Book excerpt: (U) In this paper we derive an expression for the output intensity of a general Interferometric Fiber Optic Gyroscope (IFOG). The light source is assumed to be non-monocromatic with an arbitrary frequency distribution function belonging to L2 (R). This result is expanded and expressed in terms of the parameters involved in the definition of each of the four entries of the clockwise Jones matrix of a generic IFOG with an even frequency distribution. We obtain an expression for the Sagnac phase shift error and compute it for a Gaussian, rectangular, and triangular frequency distribution function. The clockwise loop Jones matrix of a fairly general IFOG model is computed. Matlab programs for computing the output intensity and Sagnac phase shift error are also included.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental and chemical sensors in optical fiber sensor technology The nature of the environment in which we live and work, and the precarious state of many aspects of the natural environment, has been a major lesson for scientists over the last few decades. Public awareness of the issues involved is high, and often coupled with a scepticism of the ability of the scientist and engineer to provide an adequate, or even rapid solution to the preservation of the environment before further damage is done, and to achieve this with a mini mum of expenditure. Monitoring of the various aspects of the environment, whether it be external or internal to ourselves and involving chemical, physical or biomedical parameters is an essential process for the well-being of mankind and of the individual. Legis lative requirements set new standards for measurement and control all around us, which must be met by the most appropriate of the technologies available, commensurate with the costs involved. Optical fiber sensor technology has a major part to play in this process, both to complement existing technologies and to promote new solutions to difficult measurement issues. The developments in new sources and detectors covering wider ranges of the electromagnetic spectrum, with higher sensitivity, allow the use of techniques that some time ago would have been considered inappropriate or lacking in sufficient sensitivity.
